The Edding No. 1 permanent marker in green with a 1-5 mm chisel tip is the classic industrial marker for writing on cardboard, metal, glass, and rigid plastics. Its bright green, alcohol-based ink is water-resistant, fade-resistant, and abrasion-resistant, ensuring visible and long-lasting markings in the warehouse or workshop. The versatile chisel tip allows for drawing fine or bold lines with equal ease.
